Struct TransitionOutcome 

pub struct TransitionOutcome {
    pub change: EventStateChange,
    pub event_type: EventType,
    pub distribute: bool,
}

A transition that occurred, and whether it may be distributed.

ASHRAE 135-2020 Clause 13.2.2.1.4 mandates four actions on every transition: store the new Event_State, store the time in Event_Time_Stamps, store the message text in Event_Message_Texts if present, and indicate the transition to the alarm-acknowledgment and notification-distribution processes. None of the four is Event_Enable-scoped; the property disables external distribution downstream (Clause 13.2.5), so a cleared bit must not suppress the first three actions, nor the alarm-acknowledgment half of the fourth.

Separating the two answers keeps that distinction in the type: None from a detector means no transition occurred, while distribute == false means one occurred and must be recorded but not sent.

Fields

change: EventStateChange

The transition itself. Always recorded, whatever distribute says.

event_type: EventType

The Event Type selected by the detector’s event algorithm, with the mandatory CHANGE_OF_RELIABILITY override for transitions to/from FAULT.

distribute: bool

The Event_Enable bit for this transition’s direction.
